Struct ReadOnlyRwLock

pub struct ReadOnlyRwLock<T>(/* private fields */);

Read-only wrapper on an Arc<RwLock<T>> contextual value.

Implementations

impl<T> ReadOnlyRwLock<T>

pub fn new(l: Arc<RwLock<T>>) -> Self

New.

pub fn read(&self) -> RwLockReadGuard<'_, T>

Locks this RwLock with shared read access, blocking the current thread until it can be acquired.

See parking_lot::RwLock::read for more details.

pub fn read_recursive(&self) -> RwLockReadGuard<'_, T>

Locks this RwLock with shared read access, blocking the current thread until it can be acquired.

Unlike read, this method is guaranteed to succeed without blocking if another read lock is held at the time of the call.

See parking_lot::RwLock::read_recursive for more details.

pub fn try_read(&self) -> Option<RwLockReadGuard<'_, T>>

Attempts to acquire this RwLock with shared read access.

See parking_lot::RwLock::try_read for more details.

pub fn try_read_recursive(&self) -> Option<RwLockReadGuard<'_, T>>

Attempts to acquire this RwLock with shared read access.

See parking_lot::RwLock::try_read_recursive for more details.

pub fn ptr_eq(&self, other: &Self) -> bool

Gets if the read-only shared reference is to the same lock as other.

Trait Implementations

impl<T> Clone for ReadOnlyRwLock<T>

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
